JOHN BAKER, OF MUSGATINE, IOVA.

HORIZONTAL PROCESS-KETTLE.

SPECIFICATION forming part of Letters Patent No. 302,314, dated July 22,1884.

Application filed October 24, 1883.

lb ail whom, it 11mg concern.-

Be it known that 1, JOHN BAKER, a citizen of the United States ofAmerica, residing at Muscatine, in the county of Muscatine and State ofIowa, have invented certain new and useful Improvements in HorizontalProcess- Kettles Used in Cooking Canned Fruit and other Articles, ofwhich the following is a specification, reference beinghad therein tothe accompanying drawings.

This invention relates to process-kettles used in preparing fruit andother articles of food in'canning the same, and it consists in certainimprovements in the construction of such process-kettles, as hereinafterfully described and claimed. I

In the accompanying drawings, Figure l is a central longitudinal sectionof a retort or process-kettle having myimprovements. Fig. 2 is a frontend view of the process-kettle, showing the same open. A designates thebody or shell of a cylindrical process-kettle constructed of wroughtironand placed in a horizontal position, as shown. I

To the front or open end of the shell A is riveted a castiron ring, a,which is provided with lugs b, and a hinge for a door, B, which has acorresponding castiron ring, a, with lugs b on its periphery, theopening within the ring being closed by a wrought-iron plate rivetedthereto. The ring a has a groove, 0, formed therein, and a similargroove, 0, is formed in the ring a of the door, these grooves beingintended to receive suitable packing for tightly closing the kettle.\Vhen the door is closed, the lugs or projections I) bear upon theprojections b on the ring a, and the door is secured by means of thelinks d, pivoted to the lugs b, and carrying the eccentric rollers d.The links are then turned forward over the lugs b, and by means of ahand-bar inserted in one of the holes in the eccentrics angle iron barsor rails, e, extending the en- (No model.)

tire length of the false bottom and secured thereto, form the guides orway for the wheels of the trucks with which the trays containing thecans are provided. The kettle, being cireular in cross-section, has thelegs f secured thereto to support it in position.

D is the main supply-pipe for steam or hot water, leading from theboiler and passing into the process-kettle under the false bottom 0,where it connects with a perforated pipe, E, which extendslongitudinally along the kettle under the false bottom. Both ends of thepipe E are closed, and the steam entering it is distributed through itsperforations and rises through the perforated bottom Oto all parts ofthe kettle.

F represents trays for containing cans of fruit, or other articles to beheated, several trays being employed in filling the kettle. As shown inthe drawings, the trays conform to the interior of the kettle, and areof suitable size to be easily placed in and removed from' The casings ofthe trays are of v the kettle. perforated sheet metal, with angle-ironsfast-- ened along the corners, and they are provided with hinged doorsG, which are usually secured, when closed, by locks and keys. To thebottom of each tray is secured an iron frame, 9, having three wheels,two being on an axle, h, and one being connected with the frame by apivot; and the tray is moved'along on the wheels in the kettle, betweenthe angle-irons or guides e.

H represents a pressure-reservoir, supported in a vertical position, thelower end being nearly on a level with the top of the process-kettle,and it is connected by a branch steam-pipe, I, with the main supply-pipeD.

K is a branch pipe, leading from the supply pipe D to a pipe, t, in anelbow of theblowoff pipe L, leading from the bottom of the kettle,andconnecting with the upper portion of the reservoir H, as shown. Onthe closed top of the reservoir H is placed a safety-valve, 7c. Thekettle is also provided with a safety-valve, m, and a steam-gage, a;also, a glass watergage, p, and a vacuum-valve, q. A thermometer toindicate temperature is usually attached to the kettle, as seen at Z.The pipes D, I, K, and L are respectively provided with stopcocks r, s,t, u, and 'v, for directing, as desired,

through the several pipes.

the passage of water or steam between the pressure reservoir and theprocess kettle ater is introduced through a pipe into the reservoir atx, or at any suitable point, the water passing from thence through valve'0 and pipe L into the process-kettle. Then the kettle is sufficientlycharged with water, all the Valves and cooks are closed except 0', whichis opened, admitting steam, heating the water, and cooking the contents.This being effected Valve 1' is closed and t and a are opened, and thesteam, rushing through pipe K to pipe L, forces the water through pipe Linto reservoir H, the

I 5 jet of steam through K entering pipe L at '13 and forming a currentand carrying the water with it.

It will, be seen from the construction described that the water may bereadily driven from the reservoir to the kettle and from the kettle tothe reservoir, as desired.

If it is desired to use the processkettle by steam alone, the reservoirand its connectingpipes are dispensed with and connection with thereservoir shut off. A drainage-pipe, M, however, in such case should beprovided for the kettle, the latter being tapped at some suitable pointin the bottom for such purpose. A drainage-pipe for reservoir II isusually attached at 2.

In my pending case No. 109,691, filed October 22, 1883, I claim in the.particular combination therein set forth a process-ket tle with aremovable lid having rims, lugs, pivoted links, and eccentrics forfastening the lid to the kettle, all of which devices pm- 80 and theirparticular combinations, as claimed in the said application, are herebydisclaimed in connection with this application.

I am aware that perforated bottoms and trays conformed in shape to theinterior of process-kettles, and trucks constructed to run on ways inkilns used for drying fruit and grain, are not new.

I claim- 1. The combination of the horizontal kettle A, the trays F,conformed in shape to the interior of the kettle, the perforated bottom0, having the guides 0, which bottom and guides are constructed andarranged to constitute a steam-distributor and a truckway, and thetrucks 9, attached to the trays and constructed to run 011 the bottombetween the guides, substantially as and for the purposes described.

2. The combination, with the kettle A, having the perforated bottom 0and perforated supply-pipe E, arranged under the said bottom,andconnected with the induction-pipeJ), of the elevated reservoir H,connected with the kettle and its induction-pipe by valved pipes adaptedto supply the kettle with water and to return the water into thereservoir, substantially as and for the purposes described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN BAKER.
